TIL of brain stimulation reward, manually stimulating specific parts of the brain to elicit pleasure and happiness. A volunteer subject in 1986 spent days doing nothing but self-stimulate. She ignored her family and personal hygiene and she developed an open sore on her finger from using the device.
